Growing a nursery of crop seedlings then transplanting them at the appropriate time is a facet of which agricultural technique?
Jobisdone [24]

Answer:

rice cultivation.

Explanation:

There are two methods of sowing a crop in the field i. e. sowing of seed and transplanting. Seeds sowing in the field is used for almost all the crops except rice in which transplantation is done. In transplanting method, plants are grown inside a nursery and when the plant reaches to a certain height, it is transported to the field. This method is done in the cultivation of paddy rice because water is present at a certain height in the field and rice is the only crop in which roots respire in water.

You are studying a population of snapdragon plants on Membata Island. In snapdragons, the dominant allele CR encodes red flowers
fredd [130]

Answer:

we will know that the allelic frequencies are for R 0.95 and r 0.05

Explanation:

We know that the population is in Hardy-Winberg equilibrium, we deduce the following formula:

p + q = 1

p2 + 2pq + q2 = 1

data

R: red flower allele

r: allele blor blanca

p would be equal to the allelic frequency R

q will be equal to the frequency allelic r

2p = RR

2q = rr

2pq = Rr

If there are 25 white flowers in 1000 plants, their frequency will be:

2pq frequency of the Rr genotype

white flower = 25/10000 = 0.0025 = rr = 2q = 0.0025

we deduce that q is equal to 0.05

we replace the data with the previous formula

p + q = 1

p = 1-0.05

we get as a result

  p = 0.95

if p = 0.95 and q = 0.05

we will know that the allelic frequencies are for R 0.95 and r 0.05
